[On-line evaluation of the cardiotocogram using computer technology].
For an analysis of the cardiotocogram obtained by the fetal monitor HP 8040A the authors used original hardware and software means, i.e. PC XT IBM compatible in connection with an intelligent analog input periphery, which preprocesses the basic information, and with a programme using a scheme originating from the Maeda's evaluation of CTG modified by Srp. After having obtained 25 tracings (more than 8.5 hours), a detailed analysis of the computer interpretation of each course was performed, i.e. of the description of individual pathogenomic phenomena of the type of baseline heart rate, amplitude of variability, accelerations and decelerations including time parameters and mutual correlations. The results of the statistic evaluation are discussed, above all those concerning the decelerations, where the interpretation is so far burdened by a higher false negativity. Proposals for further elaboration of the programme means are presented including the optimalisation of the scheme used in evaluation, the running graphic presentation of the results and further graphic outputs for documentation purposes.
